Hi, for the attached ppt file when converted with Aspose.Slides(20.8.0) to pptx, the conversion is successful, however one of the dependency files is not valid xml since it contains a characters that xml does not allow ( 0x0E).
The corrupted file path in the pptx archive is: “\ppt\slideMasters_rels\slideMaster1.xml.rels”. On the first line around the position 1160-1170 you will find one of the invalid characters.
From the xml spec it can be seen that this character is not valid (among many others).
Char ::= #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF]
Looking forward for getting this fixed,
